and the same remedy will act as a corrective of the Saw Fly, but not a cure, 

 because the pupae may be hatched in other parts of the garden, and the fly 

 will find its way to the foliage of the dressed trees. 



The dressing alluded to was applied by me to some Pear Trees two years ago, 

 by way of experiment, and attended with such good results in this individual 

 case, that I thought it would be well if it were more generally acted upon. It is 

 no new idea ; only an old one slightly modified and carefully carried out. The 

 occasion was this. Many of my Peach Trees were badly infested with red spider 

 and mildew in 18G6, and early in the spring of 1867 I dissolved 101b. of 

 Gishurst Compound in boiling water and put it into a large tub ; to this was 

 added about 30 gallons of water, and this was all brought to the consistency 

 of very thick paint by the admixture of about equal proportions of soot, lime, 

 and blue clay finely tempered, all of which were passed through an eighth of an 

 inch sieve, to keep back any coarse granular substances. The whole, when mixed 

 well together, dried of a fine neutral tint not at all displeasing to the eye. I 

 found that to paint over the branches of the Peach Trees one by one would take 

 up more time than I had at command. I therefore determined to proceed in a 

 much more summary manner, and waited until the trees were nailed in to the 

 wall, when, with a long-haired whitewash brush, we proceeded to paint over 

 both the wall and the branches as thickly as the mixture could be got to lay on. 

 As there was no pulling the branches about afterwards, we were able to lay it on 

 very thick, and it stuck fast too. 



When the Peaches were done there, was a good quantity of the dressing left ; 

 this I proceeded to apply in the same wholesale manner to some infested Pear 

 Trees, from which, for a few previous years, not 5 per cent, of the fruit was fit to 

 send to table. The results in both cases quite satisfied me of the efficacy of 

 such a dressing. The Peaches were entirely free from both red spider and 

 mildew, and the foliage being healthy, they ripened a good crop of fine fruit. 

 The Pears also were very much improved as to their health and appearance, and 

 the fruit came clear-skinned, and the greater proportion useful. The present 

 season (1868) 1 contented myself with a good syringing with Gishurst Compound 

 of about 6oz. to the gallon, and the good effects were well sustained. In the 

 Pears especially there was a large crop of fair-sized, good fruit.

ABUTILON THOMPSON!. 



INTRODUCED from Jamaica— such is Messrs. Veiteh's brief statement of 

 j^3 the history of this very ornamental plant, which is evidently a sport from 

 Abutilon striatum, a species inhabiting the mountains of Brazil, but now 

 naturalized in Jamaica. Like its parent, it has been held in some dis- 

 repute from its true character not being at first understood. Abutilon striatum 

 itself, when introduced, was grown in the stove, and soon became set down as
